TILE oriosunn.

Application filed April 9,

' My invention relates to a new and useful improvement in a tile closureand is adapted for use in closing the ends of hollow tile used inconstructing buildings, so as to prevent concrete, which is poured toform the beams and columns of the building, from entering the ends ofthe hollow tiles positioned adjacent the position of pouring the beamsor columns, or other portions of the building.

In constructing fireproof buildings, hollow tile are generally used forsupporting the floors of the buildings and concrete beams are positionedto traverse the floors of the buildings and to support the same.

In the customary method of'construction,

the hollow tiles are positioned in close en gagement with the beams andform a part of the form into which the concrete is poured. The formgenerally projects considerably below the floor, so as to form a beam inthe ceiling of the story beneath and the ends of the tiles, themselves,are usedto constitute a portion of the form. In pouring the form full ofa plastic material, such as concrete, a portion of it enters the hollowends of the tiles. This is undesirable as it does not add any particularstrength to the structure and consumes or wastes a large amount ofconvcrete.

Various means have been employed for closing the ends of the hollowtiles at these portions where they form .a part of the form into whichthe concrete is poured, such as, stuffing'the ends With paper, blocks ofwood, etc.

' In" the present invention, there is provided a device adapted forengaging in the hollow ends of the tiles which may be positioned in thetile before the same is laid in position.

An object of the invention is the provision of a tile closure of thisclass which may be quickly and easily inserted into the end of the tileand serve as an efiective closure of the same.

Another object of the invention is the provision of a tile closure ofthis class made from a thin strip of suitable material, and havingafiixing means adapted for engaging in the ends of the tiles forefficiently closing the same.

Another object of the invention is the provision of a tile closure ofthis class formed from a sheet of metal and having tongues projectingtherefrom adapted for engagement with the tile for effectively closingthe same.

Other objects will appear hereinafter.

1924. Serial No. 705,162.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood from a reference to theaccompanying drawings which form a part of this specification and inwhich,

Fig. 1 is a plan view or" the blank from which the invention is made,

Fig. 2 is a sectional view of a beam showing the invention in operation,

Fig. 3 is a sectional view taken on substantially line 33 of Fig. 2,

Fig. 4 is a sectional view taken on substantially line H of Fig. 3.

As shown in the drawings, the invention is.

adapted for use in closing the ends of the hollow tiles 7, which aresupported by suitable supporting material 8, projecting downwardly fromwhich isone wall 9 of the form, which has the bottom wall 10 and anadditional side wall 11 to provide a container for the plastic material,or concrete, 12, which is poured therein to form a beam of the building.The floor 13 is positioned on the'upper surface of the tile 7 and may beformed from any suitable material.

The tile, as shown in Fig. 3, is made with the openings 14 projectingtherethrough,

the central opening being separated from the side openings by suitableribs 15. Various forms of tiles may be used and the openings may be ofvarious shapes and sizes, as Well as numbers. lVith the use of thevarious types of tiles, a modified form of the closure would have to beused, providing affixing means for entering each of the closures. Theclosure comprises a main body 16, having projecting from opposite sidestongues 17 which are separated by suitable spaces 18. After the blank isformed in this shape, the tongues 17 are bent on the lines 19 to form anangularly extending tongue, as shown in Fig. l. which is adaptedtoengage the inner surfaces of the openings 14 in the tile 7 It is to benoted that the spaces 18 are slightly wider than the ribs 15 and thatthe tongues 1? are bent slightly above the base of these spaces 18, soas to provide a spring effect on the tongue. By forming these spaces 18slightly wider than the ribs 15 any inequalities in the formation of theribs and tile may be accounted for and any spurs, or projections, whichmay be formed. on the inner surface of the tile be compensated for, sothat,

when the tongues 17 are sprung into the forms shown in Fig. l, the samemay be inserted into the openings of the tile, the tongues engaging thetile against the inner surface of the openings. The main body ispreferably made from some sheet metal which will give a certain amountof resiliency to the tongues 17, and these tongues, because of theirangular formation, are provided with a certain amount of resiliencywhich tends to keep the tongue against the inner surface oi the openingsit, while, at the same time, permitting a flexing of the same for theirentry into the openings. The main body 16 of the closure will then beprojected across the major portion of the openings 1st, so to securelyclose them against the entry of concrete, or other plastic material,thereinto to any great extent, a slight amount of this material beingpermitted to enter at the slots 5%, which are slightly larger than theribs 15, as stat-ed. As shown in Fig. 3, the main body projects, atopposto sides of the end tongues, so as to engage the side walls of the tile.

lVith a closure of this class. constructed in this manner, the same mayhe very quickly and easily engaged in a tile in operatire position andthe engagement of the utilizing tongues in the openings of the tile aresulticiently snug to prevent any undue removal of the closure from thetile when the same is being placedin position.

The closure may he made from a single blank, as shown in Fig. 1, stampedbut in the form therein shown, or in any other desired form. dependingupon the nature of the tile with which it is intended to be used. Thetongues 17 may then, by a stamping process, be curved or bent to thedesired form, so that the closure is one that is easily made and cheaplyn'lannfactured.

l t to be noted that the closure may be easily removed from the tileafter being placed therein, should closures be inserted in a largernun'iher of these tiles than is desired to use. The closure, whileserving its function therefor, is quickly and easily detached from thetile at any time previous to the pourin of the plastic material againstthe same.

\Vhile I have illustrated and described the preferred form of structure,I do not wish to limit myself to the precise form of structure shown butdesire to avail myself of such variations and modifications as comewithin the scope of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. A tile closure of the class described adapted for use with a tilehaving a plurality of openings formed therein, adjacent openings beingseparated by a comparatively thin partition, coniprising a mainbodyportion made from a stamping; a plurality of tongues projectingoutwardly from each of the longitudinal edges of said main body portion.the tongues on each edge being in spaced relation and separated adistance greater than the thickness of said partition, said tonguesbeing angularly turned to said main body portion and adapted forinsertion into said openings for retaming said main, body portion inposition as a closure for said openings, said main body portionextending across the spaces separating said tongues, lying in engagement with said partition and the ends of said main body portion beingprojected be yond the edges of the cndmost of said openings.

A tile closure of the class described adapted for use with a tile havinga plurality of openings formed therein, adjacent openings beingseparated by comparatively thin partitions, comprising: a main bodyportion made from a stamping; a plurality of tongues projectingoutwardly from each of the longitudinal edges of said main body portion,the tongues on each edge being in spaced relation and separated agreater distance than the thickness of said partitions, said tonguesbeing angularly turned relatirely to said main body portion, and adaptedfor insertion into said openings for retaining said main body portion inposition as a closure for said openings, the tongues projected into eachof said openings being bendable independently of the tongues projectedinto the other openings, said partitions engaging said main body at theportion .line between said tongues.

In testimony whereof, I have signed the foregoing specification.
